My invention relates to cake pans and has} for one ofitsv objectsitheprovision' of a sim ple and eflicienteake panconstruction having means for permitting the quick and easy removal .ofxa cake therefrom.

AA further/object is the provision oi acake i pan having a narrow slotadj acent: the bottom i thereof in the side Wallperm1tt1ngthe-1nsertion of a tool forlooseningthe'bottom of a cake from said-pan.

bottom and a plate mounted over said'open ing with simple and eflicientmeans for bolding the plateinvposition and permitting removal of the plate'for loosening the bottom of the" pan.

. Referringwmore;particularly thedraw I ing, I'haveindicatedmy invention as'lapplied to acake pan-havinga cylindrical upright i Wall, but'itwill be understood that the pan may be madeof any desiredshape or size} I In improved baking pan Iprovide' an upright wall3 Withabottom-l at the lower edge of said upright wallg The :bottom 4 is connected tethe upright wall by 'agdouble seam 5. The seam is arranged so: that it extends downwardlybelow' the bottom-4.

, At ,one ori inore positions in the upright war 3 I provide narrow openingsfi. In the present instance I haveindicated twocof such, n 1 openings, but it willzbe apparentrthat the number may bekva-riedzas desired, Theopening'G-is. preferably formedj-"by cutting away 1 "a piece of the u oright wall 3z adjacent the seam,ias-clearlyindicated; :Thispermit's leav- [ing a recess 75in the seam at the,lower edge of the opening- 6. ThESBEL'lH 5 is arranged sothat its upper edge willnot extend above I i the top'surface of the bottom; 4. This permits insertion of a knife, not shown or' other implement through opening 6 to loosen a I cake, orqthe'like', from-the bottom .4. The

cake can then be] loosenedfrom thje wall 3 i runningaknife, not shown, down on the p A still furtherobject'is the provision of a cake: pan having a narrow slot adjacentits a cake-from I p I I v Whenthe doughis poured: intofthe, panit will beheld in the latter for baking; :The

in1'1er 1sur1ace of? the wall'and then drawing a. the knife around the interior surface of the upright wall; pTliis permits the easy removal o-fa cake frominy improved pan construction. The upright wall 3 is preferably provided opening 6. The opening at the cut-away por- "tion 9provides an vo] 3ening "10 between the ,Wire S: and wall 3. A plate ll is curvedto fit thecurvature ofthe wall and passed throughthe opening at cut-away pO1ti0I1f9" down over opening 6 and into recess 7 I The plate ll therefore closestheopening'6. so that opening at 10 being widerthan the-length of the opening 6(Will permit theusecof a plate 1]. Wide enough to easily cover saidopening The tops'end. 12 0f the plate l lsmay be bent 3 over; 2183 indicated, to provide a; handle for 'moving the plateil'l intoand out or its;op-

erative position; a s v c .v v

giso netimes itisdesirable to permit the from the interior of the surface. When this is desired the extended ends of plates; 11, maybe jusedjto-support the pan and cake in cake,,o r the like, to sweat in the pan, and thissweating will sometimes freesuch cake inverted position. -When'the cake has been.

, loosened-fromthe pan it willdrop do wn by gravity onto the surface supporting the pan. Itis desirable to offset the plates 11 as clearly indicated in the drawing, so thata number of the pans may be placed in a ver- "tical stack with one pan disposed between the oifset upper ends of the plates 11 of the pan below. This provides anestingflefi'ect and one which will maintainthe: pans in stacks to, facilitate their storing. and shipit ment. Bzy offsetting the plates 11 the pans can be placed closer together in a stack than if these plates Were not offset and one pan 'WOUldhHVG; to be setvin the top ends-of the plates of the pan below.v This offsetting of the} plates 11 gives these plates greater strength tha'n ifthey were-not offset.

It will be'noted that informing the seam ,5 that this raises the bottom 411p so thatits upper surface isxsubstantially, even withthe 75 6, therebyvsealing thelatter against, the passageof the dough i lower edge of the opening 6. This insures spacing the bottom 4 in such a position that a knife canbe inserted under the bottom of the cake without cutting into the latter in removing the same from the pan.

wardly outwardly and then upwardly at the, slots 6 to engage both the lower edges of the slides and the outer surfaces of the lower portions thereof when the slides are in position to cover the slots. That is to say, when the slide 11 is in the recess 7, as shown in Fig. 2, the upturned peripheral portion at 7 engages the lower edge of the slide and also engages 'the lower portion of the outer surface of the slide, thus effectively closing the slot 6'and preventing leakage. Leakage through the slot 6 and ast the lateral vertical edges of the slide is e ectively prevented by substantial surface contact between the inner face of the slide and outer surface of the wall 3 bythe slide fitting in the cut-away portion 9 agalnst the wire 8.

It will also be seen that the seam 5 at the slot 6 comprises a flange formed asa part of the bottom of the pan and thatthis flange is turned downwardly, outwardly and upwardly at the slot to engage both the lower edge of the slide and the outer surface of the lower portion thereof when the slide is moved downwardly in position to cover the slot, as shown in Fig. 2. It should also be noted that While the seam 5 fits closely at 13 against the lower edge portion of the wall 3, this seam is bulged gradually outward at'14 and 15 to afford the retainer for the lower edge of the slide 11, this retainer being disposed below the plane of the top surface of the bottom of the pan. When the slide is in closed position its lower end portion makes a tight fit with such retainer. The slide and pan'may both be made of sheet metal to co-operate with the'wired rim, as shown.
